Owners of Xiaomi, Redmi and POCO smartphones often encounter an unpleasant artifact: the screenshot is noticeably darker than the image on the screen at the time of shooting. This phenomenon is especially annoying when you need to save a bright picture from a game or a frame from a movie, and the output is darkened photo. The problem is not a hardware defect of the matrix, but lies in the software algorithms for processing the image.
The main reason is that it's automatic brightness control and specific content display modes, and MIUI or HyperOS dynamically changes the backlight settings depending on the application, which leads to a dissynchronization between what you see and what's stored in the buffer, and understanding the mechanics of this process will allow you to quickly eliminate the dimming.
In this article, we will look at all possible causes, from HDR settings to system services conflicts, how to adjust screen settings so that screenshots always match reality, and how to cover hidden system functions that can affect color reproduction.
Impact HDR-content and adaptive brightness
The most common reason for screenshots to darken is the active HDR (High Dynamic Range) mode. When you view content with extended dynamic range, such as YouTube, Netflix or a gallery, the smartphone automatically boosts the brightness of the backlight and expands the color gamut. However, the standard screenshot-making mechanism in Android often captures the image in the standard SDR range, ignoring the peak brightness required for HDR.
As a result, the system tries to "squeeze" bright HDR-It's a simple image that visually feels like dimming, and it's a protective mechanism that prevents color re-lighting on devices that don't support full-fledged lighting. HDR-display or when the viewer application is unable to interpret the brightness metadata correctly.
⚠️ Note: If you are taking a screenshot HDR-video, dimming is the normal behavior of the system. HDR-Screenshots can only be taken in applications that support the format HEIF with brightness metadata, or on Dolby Vision-certified displays.
And you also need to consider the light sensor, and if you were to cut the sensor off with your hand when you took the screenshot, or if you were to put the phone down, the system could instantly reduce the brightness of the backlight, and the screenshot would capture that moment of low brightness, even if you didn't notice it visually.
To minimize the effect, try turning off the autobrightness before you create an important screenshot. Go to Settings → Screen → Brightness Level and uncheck the "Adaptive Adjustment" box, which will capture the current level of backlight and prevent sudden jumps.
Vision protection and reading regimens
The second most popular reason is active blue light filtering modes, with MIUI and HyperOS having Read Mode and Vision Protection features, which work by superimposing a yellow or warm filter over the entire interface, and when you create a screenshot, the system can treat the layer in different ways: either ignore it (the screenshot will be normal and the screen will be yellow), or bake the filter into the image, making it dim and dark.
Read Mode 2.0 is particularly aggressive, and it doesn't just change the color temperature, it also changes the screen to monochrome mode or reduces the color saturation to simulate paper, and if you try to take a screenshot while it's active, it's far from what you'd expect.
Check the status of these features in the notification curtain or in the display settings. Often users forget that they have turned on the reading mode schedule, and it activates automatically in the evening.
💡
Use the button combination for screenshot only after making sure that the notification curtain does not have the "Read Mode" or "Unlimited View" icons active.
It is also worth noting the impact of the function. DC Dimming: Some Xiaomi models have a low-brightness flicker mode that can visually darken the image. OLED-A screenshot taken in this mode will transmit the real, but reduced brightness of the pixels.
MIUI optimization and game modes
The Game Turbo game accelerator is particularly noteworthy, optimizing the smartphone’s performance during games by redistributing processor resources and changing display parameters to increase responsiveness. In some scenarios, the Game Turbo forcefully reduces brightness or changes the color range to save battery power or prevent overheating.
When you take a screenshot inside the game through a standard button combination or through the accelerator menu, you can capture these "optimized" settings, and the system assumes that you don't need maximum brightness in the pause menu or in the dialog box, and reduces it.
In addition, the game accelerator settings have separate profiles for each application, check if a performance-limited or energy-saving profile is installed for a particular game.
How to disable Game Turbo intervention?
Another nuance is the "Increased Text Contrast" feature, or similar accessibility settings, which can invert colors or darken backgrounds in certain applications to improve readability, and a screenshot will capture these changes.
Third-party applications and permissions
Don’t discount third-party software, too. Many users install screenshot applications with advanced functionality (scroll, edit, cloud storage) such as LongShot or Screen Master, which have their own image capture algorithms that may conflict with Xiaomi’s system brightness settings.
If you use a third-party app, check its settings, a filter may be activated that darkens the interface or adds watermarks that visually appear to darken, and such applications may incorrectly request permission to access the screen buffer.
Android system restrictions (starting with version 10 and above) prohibit screenshots from being taken in applications with protected content (banks, streaming with DRM), in which case you will either get a black screen or a heavily darkened image with a security warning.
| Type of application | Probability of dimming | Reason. | Decision |
|---|---|---|---|
| Banking applications | High (black screen) | Data protection (FLAG_SECURE) | Impossible (security policy) |
| Video streaming (Netflix) | Medium (dark screenshot) | HDR/DRM protection | Disable HDR in account settings |
| Games (Game Turbo) | Medium | Optimization of brightness | Game Turbo settings |
| Social media (Instagram) | Low. | Reading mode / Autobrightness | Check the screen filters |
💡
Android system security limitations often prioritize brightness settings, so in banking apps, screenshots can be completely black regardless of screen settings.
Hardware features of OLED and AMOLED matrices
Modern flagships and mid-budget models Xiaomi equipped with matrices AMOLED super AMOLED. The thing about these screens is that each pixel glows on its own, and when you display darker colors, the pickles just turn off, which gives you the perfect black color, but when you try to take a screenshot of a bright white image on the screen, you can see the color of the pixel. AMOLED-a screen with the enabled autobrightness may occur short-term current restriction (APC — Automatic Power Control to avoid burning the matrix.
The screenshot can capture the moment this limiter is working, and this is especially noticeable if you're taking a screenshot of a white document or a bright page in your browser, and visually, the eye may not notice the dip in brightness, but the screenshot camera will capture it.
Also worth mentioning is True Color technology, or color calibration, which changes hue and brightness depending on ambient lighting, using a color sensor, not just lighting, which makes screen behavior less predictable for image capture algorithms.
⚠️ Attention: AMOLED-A static high-brightness image can cause a temporary burn-in residual. Do not leave screenshots with a bright white background on the screen for a long time.
Practical instructions for elimination
If you want to get the perfect screenshot without dimming, follow this algorithm of actions, first eliminate software conflicts, and then check the system settings, we have prepared a step-by-step plan that will help in 95% of cases.
☑️ Checklist settings before screenshot
First, go to the screen settings. Find Settings → Screen → Colors and saturation. Make sure you choose the standard mode, not the read mode or the high contrast mode. Switch the color scheme to Standard or Saturated Colors, but avoid P3-marked modes if you take a screenshot for the web (sRGB).
Next, check the special settings. Go to Settings → Advanced Settings → Special Features. Here you need to find the section related to color correction and make sure that all sliders are in a neutral position. Sometimes users accidentally shift the inversion slider or shade.
If the problem persists in only one particular application, try clearing its cache. Go to Settings → Apps → All apps, find the problem app, select Memory and click Clear Cache. This will reset temporary files that may have contained erroneous rendering settings.
